2005-10-29 Fernando Montiel w pts 12 Pramuansak Posuwan, Desert Diamond Casino, Tucson, Arizona, USA - WBO. Referee: Raul Caiz. Scorecards: 115-112, 114-112, 114-112. Slow paced over the first half of the contest, with the challenger sustaining a badly swollen right eye early on and Montiel (115) being caught by sharp jabs he would normally avoided, it was not until the latter realised he was falling behind on points that he started to pick up in the seventh. In the eighth, Montiel was strangely counted over after taking a left hook that was clearly low to most ringsiders and it was that incident which ultimately spurred him on to take the remaining four rounds. Although Posuwan (115) attempted to stay with Montiel, his face had become a real mess and he was being outboxed. He was also extremely tired. His problems were then compounded when he slipped over in the 12th and the referee called it a knockdown, but he dug deep to hurt Montiel with a cracking left hook immediately prior to the bell before trudging back to his corner.

Allowed time out to challenge Mexico’s Jhonny Gonzalez for the WBO bantam title on 27 May 2006, on being outpointed over 12 rounds Montiel decided to remain in the junior bantam division and was booked to make a defence early in 2007 against Z Gorres.
